Even if do the reboot of the device on the WAN side, FCIP-Tunnel does not restore. When did the reboot of BR7800, Tunnel became online.The user is doubting the problem of BR7800. The cause is not understood though supportsave is analyzed. FOS is various with v6.4, v7.1, v7.3.

There might temporarily have been a problem in the network in the user environment. If abnormality is found on the network side, does FCIP-Tunnel become a situation in which BR7800 needs rebooting?

Re: FCIP-Tunnel of BR7800 is downed. If BR7800 is not rebooted, Tunnel does not restore.

This need extra troubleshooting for find the root cause of this issue.

The best is to take supportsaves of both concerned units prior to reboot the switches.

If you have already valid supportsaves, could be good to open a support ticket.

Do you have already open a ticket to support?

Does those units are supported by an OEM?

We wish to express our gratitude for the answer.Up to now, I have been requesting the investigation to the support of Brocade. However, the cause has not been clarified from supportsave.The support is recommended to apply latest FOS to me. But, if the cause is not understood, it is difficult to upgrade the firmware.

Concretely, please teach to me if there is Defect that needs the reload of BR7800.

So I'm thinking this is a high number of potentials defects and resolutions for migrate your current FOS version to 7.4.1d version.
